So, this is not the normal way to pronounce the name, but my wife is Eleni, and when her parents named her, they decided to pronounce it EL-in-eye, as her mother didn't want her to ever be called 'Lenny.' My wife usually tells people to pronounce it just like the letters: L-N-I. :) We also have friends who named their daughter Eleni with the same pronunciation, though she always goes by 'Ella.'

I believe this name is pronounced el-LEN-ee. It is a diminutive of Elene, which is the Greek for of Helen. I absolutely adore this name, but only when it is pronounced with a Greek accent. I don't really hear the name Lenny in it, but even if I did, what's wrong with Lenny?
